Flow

Agents ask. You answer. Work resumes.

1

Local MCP

BackPing exposes a bearer-protected MCP server on 127.0.0.1.

2

Chat Relay

Questions are sent to your configured Telegram chat or Slack DM thread.

3

Typed Answer

Your reply is routed back to the exact pending request, even when multiple agents ask at once.

Boundaries

Narrow by design

BackPing does not execute commands, start jobs, stream logs, or expose a terminal. It only asks the configured user for input and returns the answer to the local MCP caller.

  • Localhost-only MCP server
  • Bearer-token MCP authentication
  • Encrypted local storage for chat tokens
  • Telegram and Slack user allowlisting

Install

Run it as a local app

npm install
npm run dev
npm run package:mac
npm run dmg
npm run package:win

Download the latest unsigned macOS DMG or Windows installer from GitHub Releases, or build locally. Unsigned builds are intended for local testing and small-team sharing. macOS may require right-click, then Open, and Windows may show SmartScreen warnings on first launch.
